SCRAPER FOR TINN'ING- MACHINES.

Application filed March 15, 1923. Serial No. 625,326.

1 0 all whom it may concern Be it known that I, JAMEs E. KANE, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Scrapers for Tinning Ma chines, of which the following is a specification.

This invention relates toscrapers for tinning machines and has for its objects to provide means for obtaining uniformity in the thickness of the metal coating applied upon the faces of the sheets, thus not only producing a better and more uniform coating upon the sheet, but also effecting a saving in the tin or other coating metal used.

The above and other objects may be obtained by constructing the device in the manner illustrated in the accompanying drawings, in which- Figure 1 is a fragmentary, longitudinal, sectional view through a tinning machine, showing the improved scraper applied thereto' Fig. 2, a side elevation of a portion of the tinning machine; and

Fig. 3, a sectional view through one wall of the tinning machine, showing the gear ing.

corresponding parts through the drawings.

A tinning machine of usual construction is illustrated at 1, the sheets being arranged to be fed into one end of the tinning ma chine between the upper and lower guiding aprons 2 and 8 to the pairs of delivery rolls 4-4 and 55.

The guiding aprons 2 and 3 may be connected. to the opposite side walls of the.

Similar numerals of reference indicatescraper, comprising the angular plate 10 mounted upon the spring arms 11, connected at their lower ends to the lower apron, the plate 10 having the inwardlyand upwardly disposed, angular flange 12, the straight inner edge 13 thereof normally extending slightly over the path of a sheet, passing from the tin pot to the delivery PATENT OFFICE,

rolls 44. The inner scraper comprises a roll 14 arranged to rotate in a direction opposite to the movement of the sheet C.

As shown in Fig. 2, each of the lower delivery rolls 4 has a gear 15 mounted thereon, said gears meshing with each other to drive the rolls in the direction of the arrows. The right hand roll 4 has a pinion I V 16 fixed thereon meshing with a pinion 17 upon the roll 14 to drive the roll 14 in the direction of the arrow.

The upper delivery rolls 5 are similarly geared together by means of the gears 18. At the opposite end of the tinning machine, a large gear 19 is fixed upon the shaft of the right hand delivery roll 4 and a similar gear 20 upon the shaft of the left hand delivery roll 5, these gears meshing with each other and a drive gear 21 meshing with the gear 20 to drive all of the rolls in the directions of the arrows shown in Fig. 2.

As the sheet shown at O passes through. I

the tinning machine and upward through the guide apron into the lower delivery rolls 44, the upper edge of'the sheet will first engage the roll 14, the inner face of" the sheet passing over the roll which operates in the opposite direction, and removes the surplus tin from the sheet, smoothing the inner face,fwhile the outer side of the sheet engages the edge13 of the scraper 10, as illustrated in Fig. 1, this scraper re,-

moving the surplus coating of tin from the outerside of the sheet.

I claim I c I 1. In combination with a tinning machine provided with a guiding apron and delivery rolls, a roller located between the apron and delivery rolls and arranged to engage the forward face of; a sheet as it passes from the apron to thedelivery rolls, means for rotating the roller in a direction opposite to the movement of the sheet, a

scraper adapted to eatend over one lip of the apron to engage the rear surface of the sheet and spring arms connecting the scraper to the apron.

2. In combination With a tinning ma- 5 chineprovided with a guiding apron and delivery rolls, a roller located between the apron-and delivery rolls-and arranged to engage the adjacent face of a sheet as it passes from the apron to the delivery rolls, and means for rotating the roller in a direc- 1 tion opposite to the movement of the sheet. In testimony that I claim the above, I have hereunto subscribed my name.

JAMES E. KANE.
